I was planning to look at it once Lukasz/Dietmar confirm that this concept
doesn't change anything fundamental in the way EAS related changes work
today. I know I suggested the change as that seem to be right way to do
but I haven't analysed if this has any negative impact on the existing
features as this change will impact all the existing platform with OPPs
above sustained performance/frequency advertised from the SCMI platform
firmware.
